I-MCB FTCQP 1 Pole 20A TPN MCB I-50Hz Electrical Miniature Circuit Breaker

Incazelo emfushane:

1. Isicelo: Okokuvikela izintambo nezinto zokusebenza ekulayisheni ngokweqile kanye nesekethe emfishane.

2. Imithetho ejwayelekile yokukhetha i-MCB.

a. Idatha yobuchwepheshe yenethiwekhi endaweni ecatshangelwe: Amasistimu we- earthing, i-short-circuit current endaweni yokufaka i-breaker circuit, okumele ngaso sonke isikhathi ibe ngaphansi komthamo wokuphuka wale divayisi, i-voltage evamile yenethiwekhi.

b. Kunezici ezi-3 zejika zokusebenza kazibuthe: Ijika elingu-B (3-5 In) ukuvikela nokulawula amasekhethi kumakhebula obude kumasistimu e-TN ne-IT.

c. ijika (5-10 In) ukuvikela nokulawula amasekhethi ngokumelene nokulayishwa ngokweqile kanye nama-short-circuits; isivikelo semithwalo ephikisanayo ne-inductive ene-inrush current ephansi.

I-Dcurve(10-20 In) ukuvikela nokulawula amasekhethi ngokumelene nokulayishwa ngokweqile kanye nama-short-circuits; isivikelo samasekhethi ahlinzeka ngemithwalo enamandla aphezulu e-inrush current ekuvaleni kwesekethe (ama-LV/LV transformers, amalambu okubhidliza).
